Just did an upgrade to Moodle 3.10.1 (Build: 20210118) and got the following three errors:
PHP opcode caching improves performance and lowers memory requirements, OPcache extension is recommended and fully supported.
The current setup of MySQL or MariaDB is using 'utf8'. This character set does not support four byte characters which include some emoji. Trying to use these characters will result in an error when updating a record, and any information being sent to the database will be lost. Please consider changing your settings to 'utf8mb4'. See the documentation for full details.
Any help tp get me back and running would be appreciated.
